' Application meag igna za szrsennno; 3 ,06 Renewedfhpril .17,1926? T This invention relates to window -case- V l ment hardware and more particularly to in open position, f

. eatch'es for holding multifold swingingsash The object of the invention is. ,to'provide v V p v "and to thewideendi'thereofis hingedlyi'con- I, nectedfa hand grip 161 the narrow end 1"? being. designed to engage a' .nOt'ch in the a casement catch made on'the gravity lever principle whereby afswinging sash isheld in'open' position until'manuallyreleased.

With the foregoing and other objects in view which will appear as thexdescription proceeds, the invention resides in the com-- bination andarrangement of parts and in the details of construction hereinafter described. and-"claimed it' being understood that changes 'in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed without departing from the spiritof the invention.

In the accompanying drawingsze- Figure 1 represents ahorizontal SGOtlOlI ofa three-sash window equipped with this improved fastener the sash being shown closed in full lines andopen in dotted lines.

.Fig. 2-represents a front elevation of thefastener with the locking catch shown in section. a

, 3 is ad'etail Sectional view takenon the line 3 -3 of'Fig. 2.

Fig. 4: is a side elevation of the catch for locking the sash inclosed' position; and v Fig. 5 is a detail perspective viewof the catch for locking the sash in open position.

'5 sash 10 being secured to sash 5 by short:

V .In'the embodiment illustrateda window frame is shown'at F in which is mounted three sash 1, 5, and 10 'thegmiddle. sash 5 being stationary and held in closed position butt hinges 11 while sash 1 is swingably mounted on the opposed edge of sash 5 by long butt hinges 2 so hat when opened sash 10 will swing over sash 5 and sash 'lwill swing vover sash 10 as shown in dotted lines inFigl.

These sash when opened are held by the fasteners 3 and 12- constituting this in-i vention and which are exactly alike hence one only will be described in detail.

Each fastener comprisesabase plate 13 screwed or otherwise secured to the inner face of the sash in connection with which it is to be used. This plate 13 has anouti wardly bulged ap'ertured' central portion 14 on which is pivotally mounted a swinging latch member 15 the bulged portion 14 oper- "QT he sw V atingltofhold' spaced from the plat'e 13' tOJ PE T it it'to swing j-freely relatively h e ei ably made wider at one end'thanthe other- Two catches 20 and; 25 are here shown 1 mounted respectively onth-e sash 5and on the sash 1O whichare designed to be engaged by; the latches 13 and 3 respectively when the sash-10 and 1 are swung in open position.v 1 o V The catches 2O ,ancl'j25' are exactly alike" and each comprises an attaching-plate 21 theiv -lever-carried sashfis to be apertured as shown at 22 for the passage of the fastening elements and provided at one edge with a laterally extending plate 23 hav y a ng notches 24in its opposite ends with whlch notehes the latch '15 is designed to engage.

By mounting the handles 16 on thewider or heavier'end of the lever-like latch 15 th1s end is madeheavier so that it will drop downward by gravity and cause the smaller end 17 to swing upwardly into locking en'- gagement with the notch24 in the lower end" of the catch arm- 28. a

It will thus'be 'seenthat when sash is swung inwardly into the dotted linejposition shown in Fig. 1' the latch'13 carried thereby will engage the catch '20 the handle 16'being foldedin the position'Show n" The sash 10 mustbe made about three- "siXteent-hsof an inch narrower than'the other two to 'clearthe wide butt hinges 2 of 'the'sash 1 when said sash is opened.

When'the sash 1 isswung into open position the latch 3 carried thereby will engage catch 25 onsash 1 0 and thereby securely lock sash 1. in op'enposition. p V

Mounted on the window frame F at 0pposite sides thereof are catch members 30 shown in the form of apertured plates havof in the sameplane as the body of the plate with a recess 32 formed between the 1,

arm and the'plate and which is designed to receive the latches carried by: the sash 1 and 10 when said sash ar'ein closed position (see Fig. 1

v 7 g'agement of the latches 3 and 13 with the:

catches 25 and 20 respectively.

From the above description it will be seen that the swinging sash 1 and 10 maybe opened inwardly. and folded one on the other over the stationary central sash 5 and be held in this position by interlocking en- When the sash 1 and are closed they are swung into the full line position shown in Fig; 1 and the latch members 3 and 13 carried thereby will engage the catch members the smaller ends 17 swinging into the recesses-32 oi. the catches and being held by gravity in this position. 7

W arious changes in the form, shape, proportion and other minor deta ls of construc- "ed to be swung to a position to overlie the lever, a catch having a notch to receive one end of the lever, and said handle portion" adapted toioverbalance thelever tofmove the lever into engagement with the catch.

I In testimony that I claim the foregoing as my ovsn, I have hereto afii'xedimy signature.
